Fluorine pyrrole bacterium acid amides is registered for preventing and treating powdery mildew of cucumber at home, and existing document has done the report of comparison system to its fungicidal spectrum.Fluorine pyrrole bacterium acid amides is the efficient medicament of preventing and treating powdery mildew, stalk break etc., but separately use cost is high and have a risk that produces resistance.
Acibenzolar English name: Acibenzolar, chemical name: benzo (1,2,3) thiadiazoles-7-carbothioic acid-S-methyl esters.Thereby Acibenzolar is resisted the diseases such as crop powdery mildew, downy mildew, stalk break by activated plant self resistance.There is no at present the composite open report of fluorine pyrrole bacterium acid amides and Acibenzolar.
Amino-oligosaccharide, English name: oligosaccharins, for D-Glucosamine is with the oligosaccharide of β-1.4 glycosidic bond connection.Amino-oligosaccharide can affect fungus spore germination, bring out that mycelia form morphs, biochemistry changes in spore, can also excite plant vivo gene, generation has chitinase, dextranase, protective plant protecting agent and the PR albumen etc. of resistant effect, and there is cell activation effect, the recovery of the plant that contributes to be injured, short root strong sprout, strengthen the resistance of crop, Promoting plant growth is grown.Prophylaxis effect and the Acibenzolar of amino-oligosaccharide to crop has similitude.There is no equally at present the composite report of fluorine pyrrole bacterium acid amides and amino-oligosaccharide.
Although Acibenzolar, amino-oligosaccharide to a certain extent inducing plant produce disease resistance, thereby resist disease invasion, make separately availability all bad, preventive effect is not high, usually can not meet the needs of actual disease control.
Summary of the invention
The object of the invention is to: provide to use in a kind of applicable agricultural, what contain fluorine pyrrole bacterium acid amides has safety, the efficient bactericidal composite of outstanding control efficiency to fungal disease.
For solving the problems of the technologies described above, inventor is by a large amount of biologicall test screenings, and unexpected discovery fluorine pyrrole bacterium acid amides and Acibenzolar or amino-oligosaccharide are composite with certain proportion, and powdery mildew etc. is had significant synergies.
On the basis of above-mentioned discovery, through composition is carried out to symphyogenetic quantitative analysis, form technical scheme of the present invention, take fluorine pyrrole bacterium acid amides as a kind of active ingredient (A), take Acibenzolar or amino-oligosaccharide as another active ingredient (B), (A) be 50 with mass ratio (B): 1-1: 50, ratio is 20 preferably: 1-1: 20.
The present composition can be prepared into the formulation that is applicable to agricultural use by known method, comprises wetting powder, water dispersible granules, suspending agent, missible oil, microemulsion, aqueous emulsion, and in preparation, the total content of active ingredient is 3%-80%.
The adjuvant using in composition of the present invention comprises that dispersant, wetting agent, antifreezing agent etc. and other are of value to the known substance of active ingredient stable and drug effect performance in storing and using, all various compositions conventional in pesticidal preparations or that permission is used, be not particularly limited, concrete composition and consumption require to determine by simple experiment according to formula.
Composition described in the invention can finished product preparation form provide, and in composition, each material mixes, and the composition of composition also can provide with single dose form, before use, directly in bucket or tank, directly mixes, and is then diluted to required concentration.
Bactericidal composition of the present invention is mainly used in the disease of the crops such as fruit tree, flowers, cotton, wheat, vegetables, especially fungal disease control.
Compared with prior art, the beneficial effect that the present invention produces is: (1), compared with single dose, this bactericidal composition is obvious to disease synergistic effect, has improved control efficiency; (2) because drug effect improves, field dosage significantly reduces, and has reduced residue of pesticide and environmental pollution, produces and use cost decline; (3) in bactericidal composition, the mechanism of action of active ingredient is different, has reduced the single selection pressure to germ, is conducive to avoid disease resistance to produce and delay the generation speed of disease drug resistance.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention is limited to absolutely not these examples.
The combination of different pesticide active ingredient being carried out composite, is effectively and the efficiently mode of one that solves at present some problems in agricultural chemicals single dose application process.Different pesticide active ingredients shows three kinds of type of action after mixing conventionally, i.e. summation action, synergistic effect and antagonism, but be specially which kind of effect, and unpredictable, only have by lot of experiments and just can know.Compound synergic is well filled a prescription, and can improve actual control efficiency, reduces the usage amount of agricultural chemicals, contributes to the generation of delaying drug resistance, is one of important means of resistance management.
The present composition is take fluorine pyrrole bacterium acid amides (A) and Acibenzolar or amino-oligosaccharide (B) as active ingredient, between them, combination has obvious synergistic function to powdery mildew, and be not only the simple addition of two kinds of pharmacy effects, be specifically illustrated with following biologicall test example.
